Japanese Stock Investment by Foreigners (Jul/25) 912.1

The weekly Ministry of Finance cross-border flow data is a low-tier release that rarely moves markets on its own, but it is the standard high-frequency read on whether foreign money is adding to or trimming Japanese equity exposure, a flow that has historically been one of the more reliable coincident drivers of both the Nikkei and the yen given how marginal price-setting in Japan sits with overseas accounts. The figure itself denotes net purchases in yen terms; the convention is that positive prints show foreigners buying Japanese stocks, and persistent runs of large positive weeks have in past episodes accompanied broad risk-on phases in the yen pairs through the FX-hedging channel rather than the equity flow itself. The distinction worth drawing is between a single week's print, which is noisy and often reversed, and a multi-week trend, which is what has tended to matter for positioning narratives. Watch the companion series on foreign bond flows and Japanese investment abroad in the same release, since the net capital account picture is where the yen transmission actually runs. As a standalone print, the signal is thin; as a trend input, it feeds directly into the foreign-demand-for-Japan thesis.
